The local paper here just did a report on crossfit in which the reporter participated for 1 month. He had nothing but good things to say, other than it was pretty damn rough.

It sound's very much like the kind of training my boxing coach had us do in addition to boxing-specific workouts. I'm a very big guy, but in decent shape. When I cut about 20 more pounds I am going to check out crossfit, hell I might check it out sooner.

my boxing coach had me doing the 300 workout 2-3x a week before i got hurted. He also highly recommended other crossfit like workouts for me. my school just started a crossfit program and i will be in attendance upon my return. i know it's going to smoke me but it will only help me get back into the shape i was in when i was training regularly.

yes, for sure^ but be very careful about your form. That's the hard part with Olympic lifting and the like: if your form's incorrect, you can hurt yourself-badly.

At the very least, doing it wrong is of little benefit. This is how the trend of machine-assisted lifting got started, trying to make exercise fool-proof. It also took outthe real benefits(except for rehab related exercises).
